I have an RV-6, 0-360 A1A, 180 HP. equipped with a Sensenich (72 FM859-1-83)
It appears that this is a climb prop. as the airplane climbs really well. The top speed however is a little lacking. My question, is this the recommended prop for this airplane?, would an 84" or 85" pitch be better and has anyone had any experience having this model prop "Twisted" or re-pitched??

What is your static RPM? Typical is 2200-2300, depending on pitch for cruise or climb and prop/engine setup. My 3 blade Catto, for example, is around 2200 RPM static. On take-off, I look for 2250 while rolling down the runway. I can just get to 2700 RPM at WOT. I did a run yesterday after tweaking the configuration of my P-Mag with my computer and EICAD program. At 5700 feet, WOT and 2700 RPM I achieved 168 KTAS.

I need more HP and aerodynamic cleanup but happy with the prop. Also, gear fairings and wheel pants make a huge difference in top speed.

I had the Sensenich metal prop on my O-320 RV-6 repitched by a local prop shop (went from 77" to ~80"). However, I suggest you return the prop to Sensenich for repitching because their equipment is better than what will be found in a smaller shop.
